What I'd like to see:
Metroid
My expectations:
Handheld with a 1600p screen that outputs at 4K wirelessly to TV's*, always locked at 60fps, special custom chip that puts sixteen Jaguar cores at 4GHz** on the same die as four Radeon R9 Nano** cores with 32GB** GDDR5**. All Nintendo games ported to HD available as part of online service, $20 a year for the entire Nintendo console library, online gameplay (with zero lag) and one free new game a month. GTA VI, Earthbound 5, Final Fantasy XVI, Shenmue 3-25, Diablo IV, Elder Scrolls VI, Pikmin 4, Splatoon 2, Resident Evil 7, Hideo Kojima all exclusive.
$250. And the online won't get hacked.
